Bitcoin is daily having a ~4% rise and fall in price. And today's price is quite similar to what was a 5 months ago and a 3 fortnights ago.
Bitcoin has an unstable price. People may argue or analyse it in many way but no one can be right everytime and the ones are right mostly due to luck.
I am not following your ~4% rise and fall on a daily basis, there was literally not much movement in price for the past two days and today i barely moved 1%, generally if there is a movement in price we would see a change and that is common in this market but now a days we are seeing stable price too which is not strange either considering the market is getting some maturity with time.
